Ecovacs X9 Pro Omni vs Roborock Qrevo S5V: OZMO Roller Flagship vs Mid-Range Value

Cleaning Performance

The X9 Pro’s 16,600Pa suction outpaces the S5V’s 12,000Pa by 38%. More importantly, the X9 Pro measured the highest sealed suction (2.76 kPa) among all 2025 flagships — meaning its effective suction at the floor is even better than the Pa number suggests. It achieves a 93% pet hair pickup rate.

The S5V still impresses. Its 92% embedded sand removal on medium-pile carpet is one of the best results at any price, and its Triple Anti-Tangle System delivers a 0% hair tangle rate. For everyday vacuuming, the S5V performs above its price class.

Both robots vacuum well. The X9 Pro’s advantage shows most on thick carpet and heavy debris loads where higher suction matters.

Winner: Ecovacs X9 Pro Omni — Higher suction, highest sealed suction ever measured, and 93% pet hair rate. The S5V’s 92% sand removal keeps this competitive on vacuuming alone.

Navigation & Obstacle Avoidance

The X9 Pro uses dToF LiDAR, RGBD sensor, and TruEdge 3D detection. It recognizes objects visually, navigates efficiently, and avoids obstacles including pet waste, cables, and shoes. Matter compatibility provides Apple Home, Google Home, and Alexa integration.

The S5V uses LiDAR and 3D structured light but lacks an RGB camera. Its obstacle avoidance is below average — it detects objects by geometry only and cannot identify specific items like pet waste or tangled cables. In cluttered rooms, the S5V bumps into objects the X9 Pro avoids.

For pre-cleared, tidy homes, the navigation gap matters less. For homes with kids, pets, or clutter, the X9 Pro’s visual recognition is a significant practical advantage.

Winner: Ecovacs X9 Pro Omni — Visual object recognition and TruEdge 3D detection versus geometry-only avoidance. The gap is substantial in cluttered environments.

Dock & Maintenance

The X9 Pro’s dock auto-empties (150-day capacity), washes the OZMO Roller with hot water, heat-dries, auto-refills water, and self-cleans continuously. The 150-day auto-empty interval is among the longest available, reducing maintenance to quarterly bag swaps.

The S5V’s dock provides auto-empty, mop wash, warm air dry, and auto water refill. For $549, full dock automation is an excellent value. It lacks hot water wash and has a shorter empty interval, but covers the daily essentials.

Both docks minimize daily maintenance. The X9 Pro’s hot water wash and 150-day interval are upgrades; the S5V’s dock covers the fundamentals well.

Winner: Ecovacs X9 Pro Omni — Hot water roller wash, 150-day auto-empty, and heat drying. The S5V’s full dock at $549 remains strong value.

Battery & Runtime

The S5V runs 180 minutes versus the X9 Pro’s real-world 115-158 minutes (advertised 200 minutes). The S5V has meaningfully longer usable runtime.

The X9 Pro’s battery life is its weakest spec. In larger homes, it may need to recharge mid-clean. The S5V handles most homes on a single charge without issue.

Winner: Roborock Qrevo S5V — 180 minutes versus 115-158 minutes in practice. The S5V runs 15-55% longer depending on cleaning mode.

Value & Price

The X9 Pro at $1,299-1,499 (typically $1,399) costs $850 more than the S5V at $499-599 (typically $549). The S5V costs 39% of what the X9 Pro does.

For $850 more, the X9 Pro buys the OZMO Roller (highest mopping score ever), 38% more suction, visual obstacle recognition, 150-day auto-empty, and Matter smart home compatibility. These are genuine, significant upgrades.

The S5V at $549 already delivers 92% carpet sand removal, FlexiArm edge mopping, 0% hair tangle, full dock automation, and longer battery life. It’s one of the best values in robot vacuums.

If mopping is your top priority, the X9 Pro’s OZMO Roller is worth the premium — nothing else comes close. If vacuuming is your priority and mopping is secondary, the S5V delivers excellent results at 39% of the cost.

Winner: Roborock Qrevo S5V — Delivers excellent vacuuming and adequate mopping at 39% of the cost. The X9 Pro is the clear choice only if mopping quality is your top priority.
